High Electron Mobility Transistor (HEMTs) Market to Reach $9.6 Billion by 2035

High electron mobility transistor (HEMT) market was valued at $5.6 billion in 2025 and is projected to reach $9.6 billion by 2035, expanding at a compound annual growth rate (CAGR) of 5.6% from 2026 to 2035. Market development is supported by increasing demand for high-frequency communication systems, energy-efficient power conversion, advanced radar technologies, satellite communications, and high-performance electronic equipment. HEMTs use a high-mobility electron channel to support high-speed switching and high-frequency operation. Gallium nitride (GaN), gallium arsenide (GaAs), and other compound semiconductor materials enable manufacturers to address different voltage, frequency, and power requirements across telecommunications, aerospace and defense, automotive electronics, and industrial systems.

Growing Digital Infrastructure and AI Computing Demand Support HEMT Applications

Increasing investment in digital infrastructure is a significant macroeconomic and technological driver for HEMT adoption. According to the International Energy Agency (IEA), data centres consumed about 415 terawatt-hours (TWh) of electricity globally in 2024, representing around 1.5% of worldwide electricity consumption. The IEA’s 2025 Energy and AI report projected that data-centre electricity consumption could reach approximately 945 TWh by 2030 under its base-case scenario. These figures illustrate the growing scale of computing infrastructure and its associated power requirements.

As data centres expand their use of artificial intelligence accelerators, high-performance servers, networking equipment, and advanced power supplies, efficient power conversion becomes increasingly important. GaN-based HEMTs can enable high-frequency switching and lower switching losses in well-designed power-conversion systems. Their potential applications include server power supplies, voltage-conversion stages, telecommunications infrastructure, and compact power electronics. Adoption depends on system design, operating voltage, thermal management, manufacturing cost, and reliability requirements. In parallel, the International Telecommunication Union (ITU) estimated that approximately 6 billion people, or three-quarters of the global population, were using the Internet in 2025. Expanding digital connectivity reinforces the need for communication infrastructure, although Internet-user growth does not directly measure HEMT demand.

GaN HEMTs Gain Attention in High-Efficiency Power Electronics

Gallium nitride (GaN) is an important material segment in the High Electron Mobility Transistor (HEMTs) Market because of its suitability for high-frequency, high-efficiency power conversion and radio-frequency applications. GaN devices are used in power supplies, telecommunications equipment, radio-frequency amplifiers, radar systems, and other applications requiring high power density or rapid switching. Their wide bandgap properties support operation under demanding electrical conditions, subject to the device structure, voltage rating, packaging, and thermal design. In power electronics, GaN HEMTs can help reduce switching losses and enable compact circuit architectures, making them relevant to next-generation server power systems and fast-charging equipment.

Manufacturers are developing GaN transistor families and application-specific reference designs to address different operating voltages and system requirements. For example, Infineon Technologies announced its CoolGaN transistor family with an integrated Schottky diode for industrial applications on April 14, 2025. The company stated that the integration is intended to reduce dead-time losses in hard-switching applications and simplify power-stage design. This development demonstrates the ongoing focus on integrating device functions to address system-level power-conversion requirements. The segment’s commercial development will depend on broader adoption across industrial power supplies, data-centre infrastructure, telecommunications, and automotive electronics. Design engineers must evaluate device availability, qualification requirements, gate-drive compatibility, electromagnetic interference, thermal performance, and lifetime reliability before transitioning from silicon-based solutions. GaN HEMTs therefore compete on total system performance rather than semiconductor characteristics alone. GaAs remains relevant in selected high-frequency and microwave applications, while SiC-based devices address different power-electronics requirements, particularly where high voltage and thermal performance are priorities.
